Wide Pair - A binary star system in which the components are so distant from one another that they evolve independently
Wien's Law - The relationship between the temperature of a blackbody and the wavelength at which its emission is brightest ...
Struve 1694 is a wide pair of nearly equal stars (5.0, 5.5; PA 326 degrees, separation 21.6")
Beta Camelopardalis features a pale yellow primary and a very wide, much fainter, companion: 4.0, 9.0; PA 208 degrees, separation 80".
The double f Eri is a wide pair consisting of a 4.9 mag and a 5.4 mag component.
The binary p Eri lies just north of alpha Eri. Its a wide pair of orange stars of 6th mag.
Omicron2 Eri (also called 40 Eri) is a striking triple star system.
In a very clear, moonless night it is possible to see the wide pair of 5th mag stars. Each star of this double is an double itself. But to resolve them a telescope with at least 60 mm aperture and a high magnification is needed.
Note the difficulty of being certain that one is dealing with multiple images of the same quasar in very wide pairs. The classic case is that of 1146+111, trumpeted widely by Turner et al.
Kitalpha, the constellation's brightest star, lies just to the right of center, while much brighter Enif in Pegasus dominates the lower left corner. Delta Equ is the left-hand star of the wide pair up and to the left of Kitalpha, ...
